The tiobe index always seems to be way out of line with the other indices out there. Nobody but tiobe ranks VB.net above c#. Also the other day I read that Lazarus isn't taken into account in terms of assessing the popularity of object Pascal, because Lazarus is an IDE, not a language. Tiobe also seen to be constantly tweaking the methodology such that if you look back at historical rankings they can be totally different to the rankings for the same period that were reported historically. Which is verging on the dishonest. It would be like a tipster going back and revising his tips after the fact.
